If this is the original operating system you can download the drivers at the hp support website.

Just type in your model number (can be found on a white sticker on the bottom of your laptop).The pci simple communications controller is the phone modem.And the vga graphic adapter is your video or video card.

the
lack gaming abilities of the X3100 integrated graphics chipset on the
other hand really put a damper on any fun with this notebook. Without a
more powerful dedicated graphics chipset, you won't be able to play
current or even last generation games without horrible frame rates, or
even getting the game to load at all. Another downside to the X3100
graphics on this notebook is the removal of the HDMI port (come
standard in higher configurations), leaving you with only VGA out for
connection to a larger display.

You may not have sufficient video RAM.
You may be able to increase the size of the video RAM from the BIOS setting.
If this doesn't work then the video card cannot handle the games graphics and there is no way you can upgrade/change the graphics card as it is part of the motherboard.
If you want to play realistic graphics/high resolution games, then get a desktop computer, you can configure/setup these computers with greater computer power, memory and high performance graphics cards.

i'm afraid you wont be able to play any games on this unit as it has only an onboard graphics adapter runing at 8MB minimum and probably 32MB maximum as it is being shared with your system memory, so there wont be any change if you download the latest drivers as they only work the graphics not upgrade them.
even some of the latest notebooks cannot play games very well unless they are more expensive models with dedicated graphics cards and not onboard graphics.
